Rt/W Knocker(?)

This is my first character-build attempt, so try not to flame me too much >

Profession: Ritualist/Warrior

Name: Knocker

Type: PvP i think

Category: Interrupt//Support

Attributes:
Communing - 15 ( 12 + superior )
Spawning Magic - 14 ( 12 + helm + minor )
Channeling Magic - 3

Skills Set :
Shelter - Binding Ritual. Create a level 8 spirit. Allies within its range cannot lose more than 10% maximum Health from a single attack. When this Spirit prevents damage, it loses 30 Health. This spirit lasts 60 seconds.
Union - Binding Ritual. Create a level 8 spirit. Whenever an ally in its range takes damage, that damage is reduced by 15 and the Spirit takes 15 damage. The Spirit dies after 60 seconds.
Earthbind - Binding Ritual. Create a level 10 spirit. All non-Spirit foes knocked down within its range are knocked down for at least 3 seconds. Whenever this happens, this Spirit loses 25 Health. This Spirit dies after 45 seconds.
Grasping was Kurong {Elite} - Elite Spell. Hold Kuurong's ashes for up to 24 seconds. When you drop his ashes, all nearby foes are struck for 14 lightning damage and knocked down.
"None Shall Pass" - Shout. All nearby foes that are moving are knocked down.
Feast of Souls - Spell. Destroy all nearby allies' Spirits. For each Spirit destroyed in this way, all party members are healed for 97 Health.
Signet of Creation - Signet. All Spirits and animated creatures in the area gain +7 Health regeneration. After 30 seconds, those spirits and creatures are destroyed.
Flesh of My Flesh - Spell. Lose half of your Health. Resurrect target ally with your current Health and 5% Energy.

Summary: The main asset/use of this build is probably interrupting and just messing up the enemy's strategies by knocking enemies down. This build can also be used to help a spiker team, or maybe even help out allied casters who are being chased by warriors etc.

Notes & Concerns:
- Although Ritualists generally use long-range weapons, this build might be fine with melee weapons such as swords/axes as well, but the problem is that Ritualists are quite squishy.
- You could replace Feast of Souls with some other healing spell if you wish not to sacrafice too many spirits.
- Because this build is not a Ritual Lord or something like that, the main focus is not to keep Shelter/Union up as long as possible, although that could help. It's totally up to you.
- The attributes are like that because 15 Communing gives Earthbind another level, and 14 Spawning Magic gives Signet of Creation another +1 regen.
- You could also adjust the attributes so you get more damage from Kuurong or etc.

EDIT: BTW, my reason for this build is just to see if I can come up with something with Rt/W, so please try not to suggest other secondaries in your responses :P
EDIT#2: Fixed attributes, thanks Aug.
